Agronomic evaluation of calcined crandallite from three Brazilian phosphate deposits
(TAYLOR & FRANCIS INC, 2008)
Samples from the weathering mantle containing crandallite of three Brazilian phosphate deposits, Tapira, Catalo, and Juqui, were characterized, calcined, and agronomically evaluated. The calcination process increased total ...
Kaolinitic calcined clays - Portland cement system: Hydration and properties
(Elsevier, 2014-08)
This paper examines the influence of type of kaolinite in the raw clay on the performance of calcined clays as supplementary cementing materials. Two kaolinitic clays were characterized, calcined then ground and used as ...
Effects of calcining conditions on the microstructure of sugar cane waste ashes (SCWA): Influence in the pozzolanic activation
(ELSEVIER SCI LTD, 2009)
in this paper a study of calcining conditions on the microstructural features of sugar cane waste ash (SCWA) is carried out. For this purpose, some microparticles (< 90 mu m) of sugar cane straw ash and sugar cane bagasse ...

Heating rate and temperature effects on the BaTiO3 formation by thermal decomposition of (Ba,Ti) organic precursors during the Pechini process
(2008-01-15)
Different thermal treatments for the synthesis of BaTiO3 powder obtained through the Pechini method were studied. The synthesis of BaTiO3 starts at 150 °C by the thermal dehydration of organic precursors. The usual inevitable ...

Synthesis of photoluminescent β-Ga2O3 nanostructures using electrospinning method, and control of length-diameter ratio by calcination heating rates
(2019-01-01)
Nanofiber precursors of PVP-Ga(NO3)3 were synthesized through the electrospinning technique, and monoclinic β-Ga2O3 patterns were later obtained through the calcination method. During the annealing process, the nanofibers’ ...
